## Questions & Answers

**Q: Is this fan suitable for ceiling fittings**
A: The spec from the manufacturer states that if used as a ceiling fan you should not use a pull cord switch. Also you must fit a condensation trap.

**Q: What are the unit measurements - understand duct is 4 inch but I would wish to cover up where existing unit is which is 6.25 inches square.**
A: I dont know. it covered the hole in the tiles where mine was installed. tiler had tiled up to it. too lazy to remove fan to tile behind it.

**Q: could anyone tell me what corner the electrical entry is please**
A: Yes, just bought one of these. The moulding is 160mm square with 2 press outs for cable entry, 1 top,1 bottom. The connection to the pcb is at the top. You will need 100mm length from the cut out entry to the screw block terminal.

**Q: is it easy to set this up so that the over run timer works?**
A: its already set. you just adjust the run-on time. you do need a permanent live for the run-on, so a 3 core cable from the light to the fan:  perm. live/switched live/neutral.  no earth req.
